Phantom Energy: Dark Energy With W < − 1 Causes A Cosmic Doomsday, Robert R. Caldwell, Marc Kamionkowski, Nevin N. Weinberg

Dartmouth Scholarship

We explore the consequences that follow if the dark energy is phantom energy, in which the sum of the pressure and energy density is negative. The positive phantom-energy density becomes infinite in finite time, overcoming all other forms of matter, such that the gravitational repulsion rapidly brings our brief epoch of cosmic structure to a close. The phantom energy rips apart the Milky Way, solar system, Earth, and ultimately the molecules, atoms, nuclei, and nucleons of which we are composed, before the death of the Universe in a “big rip.”

Adult Male Emigration And A Female-Based Social Organization In Swift Foxes, Vulpes Velox, Jan F. Kamler, Warren B. Ballard, Eric M. Gese, Robert L. Harriqson, Seija Karki, Kevin Mote

United States Department of Agriculture Wildlife Services: Staff Publications

Members of the family Canidae are distinguished from other carnivore families by pair bonding and male care of the young. Because of the importance of food provisioning and territorial defence by males, social structure among canids is shared or even dominated by males. However, small, insectivorous species of canids show little male parental care, although whether social structure differs from other canids is unknown. We combined data from three independent research projects on a small canid, the swift fox, to help elucidate the social organization of this species. Based on data on movements of 35 adult mated pairs and the …

An Economic Analysis Of A Simple Structural Method To Reduce Road-Kills Of Royal Terns At Bridges, Stephanie A. Shwiff, Henry T. Smith, Alice M. Bard, Terese V. Harbor, Richard M. Engeman

United States Department of Agriculture Wildlife Services: Staff Publications

Royal terns (Sterna maxima) in Florida are listed as a “species of special concern” by the Florida Committee on Rare and Endangered Plants and Animals (Egensteiner et al., 1996). These birds live along the Atlantic and Gulf coasts of Florida throughout the year (Egensteiner et al., 1996); their winter range along the Atlantic Coast of the United States is from North Carolina south through Florida (Clapp et al., 1983), with the Florida population augmented by terns migrating from breeding colonies farther north. Collisions with vehicles cause many marine bird road-kills at some coastal roads and bridges in Florida …

Secure Remote Control And Configuration Of Fpx Platform In Gigabit Ethernet Environment, Haoyu Song

All Computer Science and Engineering Research

Because of its flexibility and high performance, reconfigurable logic functions implemented on the Field-programmable Port Extender (FPX ) are well suited for implementing network processing such as packet classification, filtering and intrusion detection functions. This project focuses on two key aspects of the FPX system. One is providing a Gigabit Ethernet interface by designing logic for a FPGA which is located on a line card. Address Resolution Protocol (ARP) packets are handled in hardware and Ethernet frames are processed and transformed into cells suitable for standard FPX application. The other effort is to provide a secure channel to enable remote …

Placing Monitoring Devices In Electric Power Networks Modeled By Block Graphs., David Wayne Atkins

Electronic Theses and Dissertations

The problem of monitoring an electric power system by placing as few measurement devices in the system as possible is closely related to the well known vertex covering and dominating set problems in graph theory. A set S of vertices is defined to be a power dominating set of a graphs if every vertex and every edge in the system is monitored by the set S (following a set of rules for power system monitoring). The minimum cardinality of a power dominating set of a graph is its power domination number. In this thesis, we investigate the power domination number …

Winning An Independence Achievement Game., Mark C. Taylor

Electronic Theses and Dissertations

The game "Generalized Kayles (or Independence Achievement)" is played by two players A and B on an arbitrary graph G. The players alternate removing a vertex and its neighbors from G, the winner being the last player with a nonempty set from which to choose. In this thesis, we present winning strategies for some paths.

Synthesis Of Chiral Surfactants For Enantioselective Organic Synthesis., Kalyan Mondal

Electronic Theses and Dissertations

The first step of the synthesis of the hydrocarbon-based chiral surfactant (2) involved the methylation of (S)-leucinol to give (2S)-N-hexadecyl-N,N-dimethyl-(1-hydroxy-4-methyl-1-pentyl)-2-ammonium bromide (2.92g, 67%). The chiral surfactant was synthesized by reacting (2S)-N,N-dimethyl-2-amino-4-methyl-1-pentanol (1) with bromohexadecane (2.06g, 71%). The functionalized styrene for the polymer supported chiral catalyst (6) was synthesized by reacting (1) with 4-vinylbenzyl chloride. The polymerization was carried out with 10% of the functionalized monomer (5) (1.26g, 70.2%), 5% cross-linking agent divinylbenzene, and 85% of styrene with AIBN as the initiator. The structure of each of the products was confirmed by using FTIR and NMR spectroscopy. The activity of the …

Spectroscopic Examination Of The Catalytic Decomposition Of Hydrogen Peroxide By A Copper (Ii) Complex Of A Dissymmetric Schiff Base And An Imidazole Derivative., John D. Davis Jr.

Electronic Theses and Dissertations

Previous studies involving copper (II) complexed with a dissymmetric Schiff base and imidazole derivatives had identified catalase activity of these complexes towards H₂O₂. Reactions such as this are of great interest due to the important role of copper-based complexes in biological systems. Our research has been conducted to add to the base of knowledge regarding the efforts of other researchers to investigate copper complexes that exhibit similar reactivity as copper-based proteins towards dioxygen. The copper complex chosen for this study contained a tri-dentate Schiff base adduct which, when complexed with an imidazole derivative, limited the manner …

Mechanisms For The Origin Of Turbulence In Non-Star-Forming Clouds: The Translucent Cloud Mbm 40, Steven N. Shore, Loris Magnani, Ted La Rosa, Meredith N. Mccarthy

Faculty Articles

We present a multiline, high spatial and velocity resolution CO, H I, and IRAS 100 μm study of the high-latitude, low-mass, non-star-forming, translucent molecular cloud MBM 40. The cloud mass is distributed into two ridges, or filaments, that form a hairpin structure. Velocity channel maps indicate a highly ordered flow in the molecular gas, with the northeastern part of the filament moving away from and the southwestern filament moving toward the observer relative to the mean cloud radial velocity. Significant changes in emissivity occur over 0.03 pc, indicating large transverse density gradients along the ridges. However, the velocity field appears …

Formal Properties Of Linear Memory Types, Heng Huang, Lea Wittie, Chris Hawblitzel

Computer Science Technical Reports

Efficient low-level systems need more control over memory than safe high-level languages usually provide. As a result, run-time systems are typically written in unsafe languages such as C. This report describes an abstract machine designed to give type-safe code more control over memory. It includes complete definitions and proofs of preservation, progress, strong normalization, erasure, and translation correctness.

Growth, Conductivity, And Vapor Response Properties Of Metal Ion-Carboxylate Linked Nanoparticle Films, Michael C. Leopold, Robert L. Donkers, Dimitra Georganopoulou, Megan Fisher, Francis P. Zamborini, Royce W. Murray

Chemistry Faculty Publications

Nanoparticles of metals (Au, Ag, Pd, alloys) in the size range 1–3 nm diameter can be stabilized against aggregation of the metal particles by coating the metal surface with a dense monolayer of ligands (thiolates). The stabilization makes it possible to analytically define the nanoparticle composition (for example, Au140(hexanethiolate)53, I) and to elaborate the chemical functionality of the protecting monolayer (for example, Au140(C6)35(MUA)18, II, where C6 = hexanethiolate and MUA = mercaptoundecanoic acid). Network polymer films (IIfilm) on interdigitated array electrodes can be prepared from II, based on cation coordination (i.e., Cu2+, Zn2+, Ag+, methyl viologen) by the …

Explaining And Predicting Patterns In Stochastic Population Systems, Shandelle M. Henson, Aaron A. King, R. F. Costantino, J. M. Cushing, Brian Dennis, Robert A. Desharnais

Faculty Publications

Lattice effects in ecological time-series are patterns that arise because of the inherent discreteness of animal numbers. In this paper, we suggest a systematic approach for predicting lattice effects. We also show that an explanation of all the patterns in a population time-series may require more than one deterministic model, especially when the dynamics are complex.

High-Field Measurements Of Electron Decoherence Time In Metallic Nanowires: Switching Off Magnetic Impurity Spins, P. Mohanty, Richard A. Webb

Faculty Publications

We report low-temperature measurements of electron decoherence time in a series of pure gold wires, 18 nm thick and 30 nm wide. At fields up to 15 T, large enough to polarize any concentration of magnetic impurity spins, conductance fluctuation measurements show almost no temperature dependence of the decoherence time below 300 mK, both in the correlation field for interference and the root-mean-square value of the fluctuations. Combined with previous low-field weak localization measurements on samples from similar material, our experiment suggests that the ubiquitous saturation of decoherence time in these samples is not due to any mechanism based on …

Hlanagement Of Carnivore Predation As A Means To Reduce Livestock Losses: The Study Of Coyotes (Canis Latrans) In North America, Eric M. Gese

United States Department of Agriculture Wildlife Services: Staff Publications

Many carnivore populations throughout the world are declining due to expansion of human populations, habitat loss, illegal poaching, legal hunting, disease, habitat fragmentation, declines in native prey, and increased competition with livestock and other human land uses. A major obstacle facing conservation efforts, reintroduction programs, and recovery plans for many carnivore species throughout the world is the continual issue of depredations by carnivores on agricultural interests (hlech 1996). In the United States, efforts to reintroduce and/or recover wolves (Canis lupus) and grizzly bears (Ursus arcios) in the northern Rocky Mountains has been met with much opposition …
